Air pollution is connected to a variety of long-term health problems, according to a new study.
According to the researchers, the greatest connections were seen for co-occurring neurological, respiratory, cardiovascular, and prevalent mental health problems such as sadness and anxiety.
According to a study, exposure to traffic-related air pollution is connected with an elevated risk of a variety of long-term physical and mental health issues.
According to the researchers, this is the largest study ever conducted on over 364,000 (over 3.6 lakh) people in England to investigate whether air pollution exposure is linked to the occurrence of multiple long-term health conditions.The study, which was published in the journal Frontiers in Public Health, found that high levels of traffic-related air pollution – fine particulate matter (PM2.5) and nitrogen dioxide (NO2) – were linked to an elevated risk of at least two long-term health disorders.
According to the researchers, the greatest connections were seen for co-occurring neurological, respiratory, cardiovascular, and prevalent mental health problems such as sadness and anxiety.
“People who have more than one lengthy health issue have a worse quality of life and a larger dependency on the healthcare system,” said Amy Ronaldson, the study’s first author and Research Associate at King’s College London.
“Our research has shown that persons who reside in locations with higher traffic-related air pollution are more likely to have several health issues,” Ronaldson added.

However, the study does not prove that air pollution causes multimorbidity, but it does, according to the researchers, warrant further research in this area.
They examined data from UK Biobank, a large-scale biological database and research resource that contains anonymized genetic, lifestyle, and health information from half a million UK individuals aged 40 to 69.
Participants were evaluated for 36 chronic physical and five mental health disorders. The presence of two or more of these conditions was defined as multimorbidity.
Physical and mental health data from the UK Biobank in 2010 were connected with the estimated concentration of air pollution at the participants’ homes.
The study discovered that participants exposed to fine particulate matter concentrations greater than 10 microgrammes per cubic metre (g/m3) had a 21% increased risk of two or more co-occurring conditions compared to those exposed to concentrations less than 10g/m3.
The weakest link in the fight against air pollution
The study found that participants exposed to NO2 concentrations greater than 30g/m3 had a 20% higher probability of having two or more co-occurring conditions than those exposed to NO2 concentrations less than 20g/m3.
Increased exposure to both PM2.5 and NO2 was connected to a greater severity of the co-occurring conditions among individuals with multiple disorders, according to the study.
“How air pollution affects multiple organs and systems at the same time is not fully understood,” said Ioannis Bakolis of King’s College London. “However, there is some evidence that mechanisms such as inflammation, oxidative stress, and immune activation could be triggered by air particulates, which can cause damage to the brain, heart, blood, lungs.
